English Guide to Using this Manual Symbols in text WARNING Pictograms Pictograms that appear on the machine are explained in this Instruction Manual. Depending on the machine and equipment version, the following pictograms may appear on the machine. Fuel tank; fuel mixture of gasoline and engine oil Warning where there is a risk of an accident or personal injury or serious damage to property. NOTICE Caution where there is a risk of damaging the machine or its individual components.
English When the machine is not in use, put it down safely so that it does not endanger anyone. The machine must be secured against unauthorized access. The user is responsible for accidents or hazards to third parties or damage to their property. Hand over or lend the power tool only to persons who are familiar with this model and its handling – always give them the instruction manual as well. The use of noise-emitting machines may be restricted to certain times by national or local regulations.
English Wear safety boots with steel toe caps and nonslip soles. WARNING To reduce the risk of eye injuries, wear tight-fitting safety goggles conforming to standard EN 166. Make sure that the safety goggles fit correctly. Wear a face mask and make sure it fits correctly. A face mask alone is not sufficient to protect the eyes. Wear a hard hat wherever there is any risk of falling objects.
English Cut-off machine, spindle bearing Correct spindle bearings ensure the concentricity and axial running of the diamond-tipped abrasive wheel – if necessary, get it checked by an approved dealer. Abrasive wheels Selecting the abrasive wheels Abrasive wheels must be approved for hand-held cutting. Do not use other cutting wheels and attachments – risk of accident! Abrasive wheels are suitable for different materials: Observe the identification of the abrasive wheels.
English – Slide control / master control / stop switch must move easily to STOP or 0 – Check that the spark plug boot is secure. A loose boot can lead to flying sparks which may ignite the escaping fuel/air mixture – risk of fire! – Never attempt to modify the controls or safety devices in any way – Keep the handles clean, dry, and free of oil and dirt – important for good control of the cut-off machine.
English During operation If there is imminent danger or in an emergency, immediately stop the engine – set the slide control / master lever /stop switch to STOP or 0. Check for correct idling so that the abrasive wheel is no longer driven when the throttle trigger is released and comes to a complete halt. Check and/or correct the idle setting regularly. Have the machine repaired by a STIHL servicing dealer if the cutting wheel continues to turn nevertheless.
English In the event of changes in cutting behavior (e.g., increased vibration, reduced cutting performance), stop work and eliminate the causes of the changes.
English – An exposed pipe must be provided with a stable support that will bear its weight, using wedges if necessary – always bear in mind a proper support and the nature of the ground – material may crumble away – Always work with water and wet cutting when using diamond abrasive wheels – Depending on the version, resin abrasive wheels are only suitable for dry cutting or only for wet cutting.
English When using cutting wheels made from synthetic resin which are suitable for wet cuts only, make wet cuts only – for example, use the STIHL water connector. When using abrasive wheels made from synthetic resin, which are suitable for dry cuts only, make dry cuts only. If composite resin abrasive wheels of this type become wet, their cutting performance is reduced and they become dull. If composite resin abrasive wheels of this type become wet while working (e.g.
English Sample Applications Water must always be used for wet cutting when working with diamond abrasive wheels If fumes or smoke are anticipated (e. g., when cutting composite materials), wear respiratory protection. Composite resin abrasive wheels suitable only for wet cutting Use abrasive wheel only with water. Binding dust The abrasive wheel must be supplied with at least 0.6 liters of water per minute.
N Work along the cutting line. When making corrections, do not tilt the abrasive wheel, but always set the abrasive wheel against the workpiece anew – the cutting depth for each operation should not exceed 5 to 6 cm.
N Determine and mark direction of cut N Determine sequence of cuts N Outer diameter is smaller than the maximum cutting depth Use the upper quarter of the abrasive wheel for cutting the opposite lower side. 002BA559 AM Make one cut from the top to the bottom N 002BA562 AM Plan first, then cut. Several cuts are needed – correct sequence is important.
English Cutting Wheels 1 180BA024 AM 2 Always make severing cuts so that the abrasive wheel is not pinched 180BA025 AM N N Use wedges and/or leave ridges that are broken after cutting 4 Therefore only for use of approved and correspondingly labeled abrasive wheels with hand-held machines as per EN 13236 (diamond) or EN 12413 (composite resin).
English Diamond Abrasive Wheels Never use diamond abrasive wheels with side plating as they jam in the cut and can result in extreme kickback – Risk of accident! D-B10 For wet applications. The proper selection and use of diamond abrasive wheels ensures economical use and avoids accelerated wear.
English Built-up edges, sharpen Built-up edges take the form of a light gray deposit on the tops of the diamond segments. This deposit on the segments clogs the diamonds and blunts the segments. Built-up edges can form: – when cutting extremely hard materials, e. g., granite – with incorrect handling, e. g.
English Troubleshooting Abrasive wheel Defects ragged edges or cut surfaces, crooked cut heavy wear on the sides of the segments ragged edges, crooked cut, no cutting performance, generation of sparks poor cutting performance, high segment wear Breakdowns or tears in the parent wheel and segment Undercut 1) Cause Deviation in radial or axial run-out Remedy Contact a servicing dealer1) Abrasive wheel gyrates Abrasive wheel is dull; built-up edges with abrasive wheels for stone use a new abrasive wheel Sh
